Looks good!
I think we should protect this code with a synchronized block though. This would prevent the list of objects being cleared during the time that the list is iterated over by the draw() method. I suspect we would get a crash if the user cleared the list during this time.
Could you add a synchronized block around this line, like we do when adding an object:

If you can add that, and quickly test that it works OK on your code, I'll happily merge this in. :)

Since GameArena is already keeping track of what is added to it, it makes sense it should be able to remove everything with one function.
This implementation has been poorly tested, with only 2 different programs, but worked as expected for both them.
